"Grove did a great job in presenting all options for our new AC system and potential air cleaning systems (without making any aggressive sales pitches), and then did a great job with installing the new system. The new system has been in place for a few weeks now and is working very well - great job by Grove."

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Best Air Quality and Restoration did a spectacular job! I can't say enough about the employees. They did an outstanding job! They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently. I am very pleased with their service and highly recommended this company. I purchased a new home and had them come clean the ducts to improve the homes environment. They showed me before and after pictures and I noticed a difference right away"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"The sales rep was very attentive when coming over and designing a solution to our heat and air needs. We were able to get a large team of workers here and knocked out an entire house install in one day. Some trash and miscellaneous items were left in our yard. When we needed additional items from the sales rep he will respond back saying he will take care of it but still has not. I have brought this up to him over 4 times and I still get nothing. The price seemed pretty high, and we had to shop the price around some but the company came with good financing options and some guarantees that others could not. The mini-split units work great."

"The 2 techs first showed up after my dryer had died and cleaned the vents (inside - out and also from outside-in) as much as they could but said they needed me to have an operating dryer so that they could make sure everything was pushed out the side vent and airflow was good. They were very knowledgeable and honest which I appreciate when hiring any company without a first hand recommendation from my own friends/relatives first. They rescheduled a follow up appointment after my new dryer was delivered and were here the same morning and finished the cleaning and confirmed that everything was cleaned and working as it should now. I'll definitely hire them again next year and try to keep up an annual cleaning so it doesn't get so clogged next time. Highly recommended."
"We are very pleased with the job Dave did for us today. He was prompt and very courteous and did a professional job cleaning our carpets. Thank you for keeping the planned schedule as promised. We will recommend your company to our family and friends.

Stan"

Air Conditioning questions, answered by experts

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.
